About Relay Protocol
Relay Protocol is a logic-based puzzle game built around experimentation, spatial reasoning, and energy-based mechanics.Play solo or with another player inside a mysterious industrial facility, using energy beams, reflective surfaces, logic devices, and environmental mechanisms to solve interconnected test chambers. Each player has a distinct role, and success depends on understanding how your actions affect your partner’s side of the puzzle.Redirect lasers, activate surfaces, manipulate geometric signals, and coordinate timing-based interactions to progress deeper into the facility. Every room is built around clear rules, but the solutions require observation, experimentation, and teamwork.Relay Protocol is designed for players who enjoy clean puzzle design, minimalistic sci-fi environments, and cooperative challenges where both players matter.

Amazing game! I picked this up knowing it was a co-op puzzle, but the solo mode completely surprised me. You control both characters at the same time and the mechanics work perfectly. So if you don't have a friend to play with right now, don't worry about it, you can easily enjoy the whole game by yourself and have a blast. The puzzles are excellent and really make you think. Keep in mind it's still in Early Access, but the quality is already insanely good and you can tell it has a really bright future ahead. It's awesome to see a project made by a solo dev with so much care, you can just feel that the guy loves what he does. Highly recommend it to anyone who likes the genre. Definitely worth supporting now and watching it evolve!1 found this helpful
